I tried Killen's Barbecue in Pearland on Saturday. My dad and I got there about 9:30am and we were 8th "in line". I put "in line" in quotations because they use a deli ticketing system so that you don't actually have to stand/sit in order until about 5-10 minutes before they open at 11am. This was a nice touch as we were able to sit a picnic table and wait until about 1050am.
We ended up getting brisket, pork ribs, pork & beef sausage, jalapeno pork & beef sausage, and turkey. For sides we went with mac & cheese, creamed corn, and potato salad. The brisket had a nice bark (heavy pepper) with good smokey flavor. It was B/B+ in my book. I really enjoyed the ribs, especially with the tangy sauce that I added to it. The jalapeno sausage was badly undercooked, which was very disappointing. Mac & cheese and potato salad were both good, standard issue sides. Creamed corn was a favorite of our group.
Overall, really enjoyed Killen's. I do think it is a little overhyped, but still a really good joint overall.
